How do I import XML data using Excel VBA?

I'm trying to import data from an XML file like this:

<library>
<book>
<title>aaa</title>
<author>aaa-author</author>
</book>
<book>
<title>bbb</title>
<author>bbb-author</author>
</book>
<book>
<title>ccc</title>
</book>
</library>

(note that the third book has no value for the author)

I would like to obtain an Excel table where each book's data are displayed on one row. The problem is that I do not understand how I have to loop on the book nodes to obtain their children values.

I'm working on code like this:

Set mainWorkBook = ActiveWorkbook
Set oXMLFile = CreateObject("Microsoft.XMLDOM")
XMLFileName = "C:\example.xml"
oXMLFile.Load (XMLFileName)
Set Books = oXMLFile.SelectNodes("/book")
For i = 0 To (Books.Length - 1)
   ' I cannot understand this part
Next

Add a reference (Tools -> References ...) to Microsoft XML 6.0. This will allow you to have typed variables (Dim book As IXMLDOMNode), which will give you Intellisense.

Then you can use the following code, which iterates through all the book elements, saves the title and author into a 2-dimensional array (if they are available), then pastes the array into an Excel worksheet:

Dim oXMLFile As New DOMDocument60
Dim books As IXMLDOMNodeList
Dim results() As String
Dim i As Integer, booksUBound As Integer
Dim book As IXMLDOMNode, title As IXMLDOMNode, author As IXMLDOMNode

'Load XML from the file
oXMLFile.Load "C:\example.xml"

'Get a list of book elements
Set books = oXMLFile.SelectNodes("/library/book")
booksUBound = books.Length - 1

'Create a two-dimensional array to hold the results
ReDim results(booksUBound, 1)

'Iterate through all the book elements, putting the title and author into the array, when available
For i = 0 To booksUBound
    Set book = books(i) 'A For Each loop would do this automatically, but we need the
                        'index to put the values in the right place in the array
    Set title = book.SelectSingleNode("title")
    If Not title Is Nothing Then results(i, 0) = title.Text
    Set author = book.SelectSingleNode("author")
    If Not author Is Nothing Then results(i, 1) = author.Text
Next

'Paste the results into the worksheet
Dim wks As Worksheet
Set wks = ActiveSheet
wks.Range(wks.Cells(1, 1), wks.Cells(books.Length, 2)) = results
